Δορυφορική μελέτη των χαρακτηριστικών της υπερκυτταρικής καταιγίδας της 10ης Ιουλίου 2019 = A case study of a supercell on the 10th July, 2019 based on satellite data.
Περίληψη
The aim of this study is to identify and examine the spectral and physical characteristics of the storm that hit Chalkidiki, Greece, on July 10, 2019 using remote sensing data. Geostationary and Polar Orbiting Satellite Data (MSG-SEVIRI, Sentinel 2 and 3, GPM) were used in conjunction with ground radar recordings to study and determine the spectral characteristics of the thunderstorm cloud system, based on which, information was extracted for its physical characteristics (height, shape, topography of the top, rainfall distribution, etc.) and their temporal evolution. Storm’s physical characteristics were the basis for investigating the type of the storm (MCS, multicell or supercell). These findings were, subsequently, interpreted in relation to the synoptic characteristics of the atmosphere, as well. Regarding the implementation of the satellite products, this specific study was focused on the analysis of the channels of visible, infrared and water vapor either individually, or in combination with each other, or by differences in these channels. The presence of the visible channel of high resolution (HRV) and the color channels RGB composition played an important role in capturing and interpreting the features of the region with intense convective development. This case study storm proved to have developed supercell characteristics in a mesoscale convective system, which was created because of the favorable environment in southern Europe, and caused severe damages and 7 fatalities mainly in the Chalkidiki peninsula.
